Amidst the rich natural history of the United States, Professor Brian Cox encounters the astonishing creatures that reveal how the senses evolved. Every animal on Earth experiences the world in a different way, using a unique suite of senses to detect its physical environment.

Tracing the evolution of these mechanisms is a story that takes us through life’s journey – from single-celled organisms to more complex, sentient beings. Brian finds that over the course of 3.8 billion years, the senses have driven life in new directions and may, ultimately, have led to our own curiosity and intelligence.
